Lorien
Infinite canvas drawing/whiteboarding app
...The app runs on Windows, macOS, and Linux, and itβs built using the Godot game engine, which gives it a responsive and modern user interface across platforms. Users get features like infinite zoom, undo/redo, and a grid that stretches endlessly, making it well suited to both quick scribbles and detailed conceptual layouts. Lorien supports pressure-sensitive tablets for natural drawing, and it includes a range of basic tools β from freehand brush and eraser to shapes and selection tools β so you can mix freeform sketches with structured diagrams.
